This was the first animated feature film given the NC-17 rating by the MPAA.
Bill Timoney revealed in an interview that although he was horrified by the film's footage, he accepted a role because he needed to pay his rent, he wanted to break into voicing animation, and he enjoyed how the film's box art said it was "absolutely not for children".
Many of the characters were voiced by kids
This movie combines the three previously-released installments of the series 'Chôjin densetsu Urotsukidôji' (1987-89), omitting the sexually explicit material.
The actress credited as Rebel Joy, who voiced the girlfriend of Bill Timoney's character, was Timoney's real-life girlfriend at the time.
